Please provide documentation and certification sheets (from a Nationally Recognized Testing Lab (NRTL)) for both the batteries and SolArk inverter to show that all components are tested and certified per UL 9540.

<div><span style="color:rgb(0,0,0)">Have any of you run into this with Solark? Is the plans-checker in the wrong about the entire system needing to meet the standard and not just the batteries? The code language is kind of confusing. I can't find any documentation on Solark's website regarding UL 9540. I know Tesla and Simpliphi have recently put out documentation regarding this.</span></div>
